目标。我们描述了肩关节-肩关节韧带撕脱伤(HAGL损伤)的放射学表现及其常见的相关损伤。本文对1996年10月至2001年2月在本院诊断的6例HAGL病变进行了回顾性分析。我们复习了放射学报告、放射学检查、医疗记录和手术笔记。结果所有患者均为男性，年龄19~41岁，平均26岁。4名患者(67%)有肩关节前脱位。其中3个(50%)的HAGL病变在放射学检查中被发现，要么是通过放射学检查，要么是通过磁共振成像。一名患者患有骨性HAGL。所有患者均有相关损伤。最常见的合并畸形是：骨软骨损伤3例，肩袖撕裂3例，Bankart损伤3例，Hill-Sachs损伤2例，肩中韧带撕脱1例，肱二头肌腱部分撕裂1例，锁骨粉碎性骨折1例。结论：HAGL损伤是导致关节前方不稳定的重要原因，发生率分别为7.5%和9.4%。大多数(68%)的HAGL病变患者有相关损伤。
OBJECTIVE. We describe the radiologic findings of the humeral avulsion of the glenohumeral ligament (HAGL lesion) and its commonly associated injuries.MATERIALS AND METHODS. A retrospective review of six cases of HAGL lesion diagnosed at our institution from October 1996 to February 2001 was performed. We reviewed the radiology reports, radiologic examinations, medical records, and operative notes. All patients had undergone radiography, and four patients had undergone MR imaging of the shoulder before diagnostic arthroscopy.RESULTS. All the patients were men who ranged in age from 19 to 41 years (mean, 26 years). Four patients (67%) had an anterior shoulder dislocation. Three of the HAGL lesions (50%) were detected on radiologic examinations, either by radiography or MR imaging. One patient had a bony HAGL. All patients had associated injuries. The most common associated abnormalities were osteochondral injury of the humeral head (n = 3), rotator cuff tear (n = 3), Bankart lesion (n = 3), Hill-Sachs lesion (n = 2), avulsion of the middle glenohumeral ligament (n 1), partial tear of the biceps brachii tendon (n = 1), and comminuted fracture of the clavicle (n 1).CONCLUSION. With an incidence of 7.5% and 9.4% in two large series of patients, the HAGL lesion is an important cause of anterior instability of the glenohumeral joint. The majority (68%) of patients with an HAGL lesion have associated injuries.
